Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511840, here are decompositions:

71 + 33511769 = 33511840
83 + 33511757 = 33511840
113 + 33511727 = 33511840
179 + 33511661 = 33511840
227 + 33511613 = 33511840
239 + 33511601 = 33511840
269 + 33511571 = 33511840
293 + 33511547 = 33511840

Showing the first eight; more decompositions exist.
